Slifer the Sky Dragon

Shroud, Split Second
Slifer the Sky Dragon doesn't trigger abilities of
permanents when it enters the battlefield as you
cast it from your hand. If Slifer the Sky Dragon
enters the battlefield and it wasn't cast from your
hand, sacrifice it at the beginning of the next end
step. Slifer the Sky Dragon's power and toughness
are equal to twice the amount of cards in your
hand. Opponents creatures get -4/-0 when they
enter the battlefield, and are destroyed if this
reduces their power to 0.
